Anyone use adwords legitimately?

I'm just starting out with adwords and doing my research on it.
from what I gather here, lots of users are making multiple accounts and primarily paying using vouchers.
I'd just like to know if anyone actually legitimately uses adwords with one real account and actually buys keywords with their own real money.
If so, how much have you made with adwords?

I know this site is called Black Hat World but trying to perpetually get free advertising on Adwords with coupons is not a good idea long term. If you are serious and want to be legitimate, open one account, use a coupon if you have one and advertise.

I've used Adwords and actually paid for my clicks as do all the clients I've ever had. Not saying it worked for all of them but a large majority made profits they would not otherwise have made. You have a business, you have to advertise if you're going to make sales and Adwords is one way. Don't forget there's other PPC services out there and that you can use this information for your SEO efforts. Good luck.
